UNCOUPLING DEVICE.

To au w/wm zt may concern.'

Be itknown that I, GEORGE C. MURRAY, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and' 'useful' Improvements in Uncoupling Deypairs or replacements become necessary in the mechanism. y

These and otherobjects will be set forth and shown in the following specification and accompanying drawing, in which-- Figure 1 is a perspective portion of the end of a car showing my mechanism applied thereto.

Fig. 2 is a perspective of a detail of the mounting of my uncoupler.

Fig. 3 is a similar View of another detail.

Fig. 4 is a section taken through a portion ofthe mounting of the uncoupler.

Fig. 5 is a perspective detail view of a slight modification.

Like numerals refer to like elements throughout the drawing, in which designatos generally the usual form of coupling mechanism having the coupler-pin 11 slidablymounted therein, this coupler-pin being provided with a loop or eye 1P. lvhat I term uncoupler rod 12 has angularly disposed arms 12- 12"d -The arm 12;a is of suf.- icient size to extend through the eye 11P- of the coupler-pin and it loosely lits therein and permits sliding of the coupler 11 theren along, as will be obvious. The extremity of the other arm 12b is looped to form an as clearly shown in Fig. 1.

An ,operating rod 13 is provided with the downwardly extendingr handle portion 13*l and is rotatably mounted or journaled in the bearing; members M, 15, respectively. 'The li ringr member 14 comprises a bracket or casting centrally apertured at' 14'* and is spcification of Letters raient.

secured to the end sill'of the car by bolts, 55

rivets, or the like, 14.".

The supporting member 15 comprises a memberl, which I term a seat member, and the locking member 15", see Figs. 2 and 3. Thel former comprises a plate 15 apertured at 15,(l for fastening to the end sill of the car. A seat or chair 15e is carried by the platec15c and is concaved, as indicated by the numeral 15f, to furnish a journal bearing for the rod 13. the plate 15c is provided with the curved/ flanges 15g spaced apart as shown in Fig. 2. At its lower portion the plate 15 has apertured at 15. The locking member 15b-is provided with the intle .15k in which extends downwardly tlie U-shaped loop 15, the same being bent directly doWnwardly from the 'pintle 15k and then looped as shown in Fig. 3. 'Carried by the loop -At its upper portion 15 are the spaced apart outwardly'extend- 75 1n locking position, vin which `position a. 85

cotter-pin4 16 may be passed therethrough and spread'at its end, as shown in Fig. 1. Afdjacenv e iocking member 15b the rod 13 1s offset, as indicated by numeral 13b, for a purpose to be hereinafter described.

The qvc 1.2c of the uncoupling rod 12 is loosely mounted on the offset-portion 13" of the y:ind 13 andv extends outwardly therefromf substantially at right angles in the form shown inthe drawings, the length of the arm 12b being determined by the position of the coupler-pin 11 with reference tol the yposition of the operating' rod 13. The rod 13 has the portion 13 bent at rightangles to the olset portion 13b and a portion 13 thereof is reversely bent substan-4 tially at right-angles to portion 13 extending under the arm 12b of rod 12. At its extremity 'the portion 13d is upturned slightly, as indicated at numeral 13.

Vihen the device is in assembled position, as shown in Fig. 1, it is apparent that the couplerfpin may be raised to lock set p0- `sition by raising the handle portion 13l of rod 13 whereupon the reversely bent portion 13d of the rod will coact with arm 12h of coupler rod 12, the saine being in effect fulcrumed at its eye 12c so that the said movement of the rod 13 will raise the couplerpin 11 to its lock set position, in which an ordinary coupling `construction Will be retained until the cars are again coupled. One advantage of my construction is that the operating rod may drop to position shown in Fig. 1, while the coupler is in lock set position, the rod 12 being maintained in its upper position by the coupler-pin. Inasmuch as regulations and requirements demand-` that uncoupling mechanism "permit in and out movement of the draw-bar mechanism and lateral movement thereof, I have provided for such movements by making the rod 12 of such diameter as to fit loosely in the eye 11a of the coupler-pin, thereby providing for a certain amount of relative sliding movement of the latter with respect to the rod 12.V At the same time the loose mounting of the eye 12c upon portion 13b of the rod 13 provides for a certain amount of pivotal movement of the rod 12 laterally relativetrr the rod 13, as will be apparent. The upturned portion 13 will prevent movement of the rod 12 out of operative position Withrespect to the operating rod 13, as will be apparent.

In use it is very often the case that the uncoupling rods becoine bent or twisted or for other reasons require replacement, and

to render such repair and replacement easy of accomplishment, I have provided the locking means 15 described above. When it is desired to remove the coupler mechanism it is merely necessary to remove the cotterpin 16, raise the locking member 15b and slide the rod 13 bodily to one side until the rod 12 is removed from engagement with the coupler-pin 11, when said rod may be partially rotated and removed around the portions 13, 13d and 13" of the rod 13. If it is desired to remove the rod 13 also the same may be swung outvardly to permit the operating handle 13 to be drawn through the aperture lll being enlarged at each end, as shown in -rod 13 of member l-l, the said aperture Fig. 4, to expedite such withdrawing. lVhen in assembled position the rod 13 is prevented from accidental removal and too great a lateral. movement by the oset therein, which will contact with the loc-king member 15 to limit such movement.

It will be apparent that I have provided mechanism which Will operate eliiciently in uneoupling the car and one which is not only inexpensive to manufacture, but which may be readily attached to and detached from a car, this feature enabling repair on the mechanism without removing the car from active service, which is a great advantage.

In Fig. 5 I have shown a modification in which the end 13' of rod 13 is extended upwardly above and then rearwardly over the arm 12b being then bent downwardly at its end to terminate adjacent the portion 13c of rod 13. This will permit, as is obvious, suiicient up and down movement of arm 12b with similar movement of the draw-bar, and will also prevent accidental removal oi' the rod 12 from rod 13', this construction serving also to limit sliding of rod 12 on It Will be apparent that m device is susceptible of many changes anr modifications, and I do not Wish to be restricted to the form shown and described beyond the scope of the appended claim.

What I claim is:

A11 uncoupling mechanism comprising an operating rod rotatably mounted on a car, said operating rod being provided with an o'set portion and a reversely spaced therefrom, and an uneoupling rod adapted to engage the coupler-pin to said car, said uncoupling rod being tulcrumod on said oiset portion of said operating rod, said reversely bent ortion'Of Said operating rod being arranged) to Contact with and operate said uncoupling rod upon proper movement of said operating rod.

In testimony whereof, I have subscribed my name.
